Phylogenetic analysis based on 5.8S/ITS sequence indicated Armillaria luteo-virens has a distant phylogenetic relationship with other genera of Tricholomataceae. Phylogenetic analysis based on two IGS-1 sequences indicated there were significant differences between the IGS-1 sequence of Armillaria luteo-virens and that of other species of Armillaria.

One was the pqsA' positive expression plasmid constructed by cloning the pqsA'-lacZ fusion digested from pYHP441 into miniCTX-1, whose sequence was then integrated into wild type PAO-1 chromosome by biparental mating procedure. The other was pqsA-E operon knock-out plasmid whose sequence between pqsD and pqsE operon was inserted by tetracycline cassette by the site specific insertion mutagenesis strategy and the mutant constructed by biparental mating of S17-1 that harbored the plasmid and pqsA' positive expression mutant.

一种是酶切质粒pYHP441获得pqsA'-lacZ片段后，亚克隆入质粒miniCTX-1中，构建成PqsA'的阳性表达质粒，随后将构建的质粒，通过双亲交配过程整合入野生型铜绿假单胞菌株PAO-1染色体组中；另一种是通过点特异插入诱变策略，将四环素基因盒插入启动子pqsD和pqsE之间，构建的阴性质粒转化入大肠杆菌S17-1株后，和上述pqsA'阳性表达突变株进行双亲交配过程。

The intergeneric phylogenetic trees of water lilies showed that Nelumbo and Ceratophyllum form a sister group, but with relatively high sequence divergence, supporting that place the two genera into two distinct families; and Brasenia and Cabomba form a sister group, with relatively low sequence divergence, supporting that the two genera were placed the same family Cabombaceae.

结果表明：莲属与金鱼藻属构成姐妹群，但序列分歧度较大，支持将两个属独立成科的观点；莼菜属与水盾草属构成姐妹群，且序列分歧度较小，支持现有的莼菜科处理。

Roots of five species of Calanthe and two species of Phaius from north, midland and south of Taiwan were collected for the isolation of orchid mycorrhizal fungi. Total for 104 isolates of fungi were isolated. They are identified respectively by the traditional method or DNA sequence. Results showed thatTrichoderma and Mucor were most often isolated fungi. The DNA sequence results showed that only Xylaris was most common fungus.
